Hi! I've been using my tablet pretty well stationary on my desk or the last year. When I installed windows 7 beta, I enabled the tablet function and it worked fine. Fast forward a few months; I installed windows 7 professional, but never could figure out how to enable tablet functionality, but I haven't really missed it until now. The computer doesn't detect the stylus near the screen. I've enable, disabled and re-enabled Tablet PC Components. I don't know what to do...
